Definitions

  • the present invention relates to a vaporizer.
  • a vaporizer constituted by a heat exchanger in which a heat transfer fluid transfers heat to a liquid to be vaporized, the liquid flowing in at least one U-shaped tube connected to a plate.
  • This vaporizer may for example be a backup vaporizer, which vaporizes cryogenic liquid to a network, to compensate the flow from a cryogenic unit.
  • This system is usually powered by a cryogenic pump and the vaporized liquid in the pin is sent to the customer when the air separation unit stops.
  • a vaporizer 4 consisting of a cylindrical chamber 7 and a hemispherical dome, both being separated by a vertical plate 13 pierced with openings. These openings are connected to U-shaped pipes so that one end of the pipe is attached to an opening in the lower part of the vertical plate 13 and the other end is attached to an opening in the upper part of this plate .
  • the dome is divided in a sealed manner into an upper part 5 and a lower part 3 by a horizontal flat plate forming a partition 6.
  • a liquid to be vaporized is introduced into the lower part 3 which forms a feed chamber and circulates in tubes U-shaped 17.
  • the liquid arrives towards the upper part 5 of the dome 2, which constitutes an evacuation chamber. There it is entirely vaporized by the exchange of heat with steam 9 or other heat transfer gas sent into the chamber 7 and which circulates around the tube or tubes 17. The gas formed by vaporizing the liquid is withdrawn from the upper part 5 of the dome 2. The cooled water vapor 1 1 leaves the atmosphere at the top of the chamber 7.
  • This vaporization system has a relatively long start-up time, even when the cryogenic pump sends the full flow to this system emergency, it is necessary to wait between 30 seconds and a minute before observing the full flow of vaporization.
  • An object of the invention is to reduce the commissioning time of a vaporizer and reduce the overall cost of the apparatus incorporating the vaporizer by eliminating or reducing the size of the buffer capacity.
  • a vaporizer comprising a plurality of U-shaped tubes contained in an enclosure, each tube having two ends, the tubes being arranged in at least one plane, the enclosure being closed on one side by a plate having as many apertures as there are tube ends, the apertures comprising apertures and low apertures, each tube being connected at one end to a top aperture of the plate and at a bottom end to a low opening of the plate, a dome covering the plate on the opposite side to that of the tubes, the dome being delimited by a partition orthogonal to the plane of the tubes to form an admission chamber and an evacuation chamber characterized in that the intake chamber is divided into two parts by a partition perpendicular to the plane of the tubes and the partition to form a liquid inlet chamber between the plate and the partition and a chamber on the other side of the partition, the liquid inlet from the outside of the vaporizer opening into the inlet chamber and the auxiliary chamber being arranged to receive only liquid from the inlet chamber so that the liquid coming from the outside arriving
  • the partition includes an opening towards its bottom edge to allow a circulation of liquid between the partition and the dome.
  • the volume of the inlet chamber is smaller than that of the auxiliary chamber.
  • the volume of the inlet chamber is at least two times smaller than that of the auxiliary chamber.
  • the lower openings are arranged at different distances from the partition.
  • the chamber of ad dition and the evacuation chamber have substantially the same shape and volume
  • the partition is a flat plate.
  • the liquid from the outside can enter the auxiliary chamber only through an opening in the partition or passing over the partition.
  • the liquid inlet is formed in the enclosure.
  • the liquid inlet is arranged so that in use the liquid enters the bottom of the vaporizer.
  • a cryogenic distillation separation apparatus comprising a vaporizer according to one of the preceding claims and means for supplying it with cryogenic liquid.
  • a method of vaporizing a liquid in a vaporizer in which a heat-generating gas is sent to the chamber, a liquid to be vaporized is introduced into the inlet chamber and evacuates the liquid vaporized by the evacuation chamber.
  • the improvement device according to the invention is therefore a weir system which preferentially feeds the tubes of the exchanger to the rise in production of the vaporization system.
  • This spillway consists of a solid plate open at the top and equipped with a deconcentration hole for hydrocarbon safety located at the bottom of the tank.
  • Figure 2 illustrates a vertical section of the vaporizer
  • Figure 3 shows a side view of the interior of the vaporizer of Figure 2.
  • the vaporizer of FIG. 2 differs from that of FIG. 1 in that a solid plate 21 forms a partial partition dividing the lower part 3 of the dome 2 into two unequal parts.
  • the left part of FIG. 1 corresponds to the left part of the vaporizer of FIG. 2.
  • the partition 21 is arranged substantially vertically, so that about one third of the volume of the lower part 3 is located between this partition 21 and the plate 13.
  • the partition 21 does not extend to the horizontal plate of the partition 6 and an opening 23 is formed in the middle of the partition 21 at its bottom edge.
  • the liquid enters from the outside into the space of the lower part 3 only through an inlet disposed between the plate 13 and the partition 21.
  • the opening 23 is small, the liquid accumulates in this space and the liquid level rises so that all the pipes 17 opening into the plate 13 are fed.
  • the liquid flows to the other side of the plate 21.
  • the liquid can also pass into the opening 23.
  • the invention is also applicable to the vaporization of liquids which condense at temperatures above cryogenic temperatures.
